In general, a high risk of hearing loss has been known if you continue to hear the sounds of a high acoustic pressure level, such as, listening of the portable audio and working with too loud noises. According to WHO, some 1.1 billion teenagers and young adults are at risk of hearing loss due to the unsafe use of personal audio devices, including smartphones, and exposure to damaging levels of sound at noisy entertainment venues such as nightclubs, bars and sporting events.

By measuring the characteristics of your current hearing, please try to consider the wellness of your ears and the way of natural sound reproduction. It is possible to measure the hearing of the audio range by finding the minimum point in the operation of the slider volume that you can hear the tesing pure tone for each frequency. The results are displayed in easy-to-read charts like the audiogram.

# Attention:

Please use the earphones that provided with the iPhone in the hearing test.

This application generates a test tone signal with a high gain, so please special attention to the volume adjustment.

Before the diagnosis start, please set the hardware volume control to the central position of 50%.

If the volume slider is moved to the right side, the output volume will have a large gain. So as not to be excessively large gain for your ears, please adjust it carefully.

[ATH compensation]

It is a graphical representation applied compensation of the frequency characteristics to fit the lowest audible value of human beings. If it is a higher level and flat as possible, the graph is estimated to be good condition of your hearing.

In addition, the Absolute Threshold of Hearing (ATH) is the minimum sound pressure level that can be detected by hearing noise-free environment. It has been corrected to be a flatter graphical representation for each frequency in the case of normal hearing. However,
it may display levels vary significantly, due to the surrounding environment and individual differences.
